We’re building a tech-hedge-fund-style intraday algorithmic trading platform and are looking for a Rust/Python Quant Developer with strong data and cloud engineering expertise. You’ll work on everything from trading signal logic to large-scale data pipelines and infrastructure automation. You’ll join our core team of two highly experienced quants who are also full-stack developers with deep data and cloud expertise — the bar is high, but the learning curve and impact are massive. It’s absolutely fine if you’re not yet an expert in every area — you’ll grow into it quickly working alongside us. We’ll mentor and support you closely throughout the process. Our system goes live next week, and you’ll play a key role in evolving it from a powerful launch version into a world-class trading engine. Our overall team (core + non-core) currently consists of 8 people. 🧠 --- Responsibilities --- - Design and implement scalable, modular, and testable trading and backend components (e.g., bot signals for technical indicators, orderflow, price action, ML-based algorithms) in Rust - Improve and extend our strategy optimization framework in Rust - Develop and maintain TB-scale Dagster/DBT ETL pipelines in Python - Optimize data ingestion, storage, and queries for TimescaleDB/PostgreSQL - Maintain and enhance our K3s cluster on Hetzner Cloud (autoscaling, reliability, observability) using Terraform, Helm, and Kustomize - Build and extend Grafana dashboards and alerting systems for market data, bot observability, and system health - Collaborate closely with our bot operators to detect, analyze, and fix issues in live trading 🔍 --- Requirements --- Core: - Strong experience in Rust (most important skill!) - Proven background in Python-based data engineering and scalable data architectures - Basic Kubernetes skills - Proficiency with the Grafana Stack (dashboards, monitoring, alerting, capacity planning) - Genuine passion for financial markets and algorithmic trading - Strong academic background and/or impressive track record - Confidence and ambition to compete at a global level with the brightest minds - Highly collaborative, low-ego mindset — typically more introverted but deeply focused and reliable - IT and coding aren’t just your job — they’re your biggest passion Nice to Have: - Strong math and ML skills (big plus for improving our optimization engine) - Solid experience with autoscaling Kubernetes (K3s), Terraform, and Helm/Kustomize on Hetzner Cloud - Experience with TimescaleDB or TigerData - Familiarity with financial data, especially Databento API (CME futures) - C# skills (Quantower or NinjaTrader integration) - Knowledge of AI/agent systems (e.g., n8n, LLMs, Reinforcement Learning) 🌱 --- What’s In It for You --- - Work on a cutting-edge, high-performance trading platform — probably the most exciting playground you’ve seen as a tech/quant enthusiast - Collaborate with a small, elite, international quant team - Risk-free, paid probation period (part-time) — ideal to test long-term fit while keeping your current job (10–20h/week over 6 months) - Remote-first culture - Possibility of a long-term collaboration if the work results meet expectations - Learn faster and deeper than anywhere else — directly from highly experienced quants and developers ⚙️ --- Process --- - Short interview (~1.5h) — no LeetCode nonsense, no live coding. Just a real, high-level tech talk between quant/tech nerds. - 6-month paid trial (part-time, $15/h) to ensure a strong mutual fit for both sides - Long-term collaboration (via Upwork) with a much higher $$ compensation Client's questions: Do you have hands-on experience with our tech stack — Rust, Kubernetes, Dagster/Python, Grafana stack, TimescaleDB, and Terraform? Which of these areas would you consider yourself an expert in? Do you have any experience with TB-scale financial data pipelines on top of a Kubernetes cluster? It’s not a must-have, but definitely a nice bonus. Do you have real world experience optimizing intraday trading strategies (in Rust) — from data to optimization to execution? If yes, describe your experience here. We’ll go bit-level deep at our interview, so ChatGPT-style answers won’t help here. Is a paid part-time probation period at $15/h acceptable for you — so we can both evaluate whether this collaboration is a strong long-term fit? Is there anything else you’d like to share about why you think you’d be a great fit for this role? We’d love to hear what excites you about the opportunity!

We’re building a tech-hedge-fund-style intraday algorithmic trading platform and are looking for a Rust/Python Quant Developer with strong data and cloud engineering expertise. You’ll work on everything from trading signal logic to large-scale data pipelines and infrastructure automation. You’ll join our core team of two highly experienced quants who are also full-stack developers with deep data and cloud expertise — the bar is high, but the learning curve and impact are massive. It’s absolutely fine if you’re not yet an expert in every area — you’ll grow into it quickly working alongside us. We’ll mentor and support you closely throughout the process. Our system goes live next week, and you’ll play a key role in evolving it from a powerful launch version into a world-class trading engine. Our overall team (core + non-core) currently consists of 8 people. 🧠 Responsibilities - Design and implement scalable, modular, and testable trading and backend components (e.g., bot signals for technical indicators, orderflow, price action, ML-based algorithms) in Rust - Improve and extend our strategy optimization framework in Rust - Develop and maintain TB-scale Dagster/DBT ETL pipelines in Python - Optimize data ingestion, storage, and queries for TimescaleDB/PostgreSQL - Maintain and enhance our K3s cluster on Hetzner Cloud (autoscaling, reliability, observability) using Terraform, Helm, and Kustomize - Build and extend Grafana dashboards and alerting systems for market data, bot observability, and system health - Collaborate closely with our bot operators to detect, analyze, and fix issues in live trading 🔍 Requirements Core: - Strong experience in Rust (most important skill!) - Proven background in Python-based data engineering and scalable data architectures - Basic Kubernetes skills - Proficiency with the Grafana Stack (dashboards, monitoring, alerting, capacity planning) - Genuine passion for financial markets and algorithmic trading - Strong academic background and/or impressive track record - Confidence and ambition to compete at a global level with the brightest minds - Highly collaborative, low-ego mindset — typically more introverted but deeply focused and reliable - IT and coding aren’t just your job — they’re your biggest passion Nice to Have: - Strong math and ML skills (big plus for improving our optimization engine) - Solid experience with autoscaling Kubernetes (K3s), Terraform, and Helm/Kustomize on Hetzner Cloud - Experience with TimescaleDB or TigerData - Familiarity with financial data, especially Databento API (CME futures) - C# skills (Quantower or NinjaTrader integration) - Knowledge of AI/agent systems (e.g., n8n, LLMs, Reinforcement Learning) 🌱 What’s In It for You - Work on a cutting-edge, high-performance trading platform — probably the most exciting playground you’ve seen as a tech/quant enthusiast - Collaborate with a small, elite, international quant team - Risk-free, paid probation period (part-time) — ideal to test long-term fit while keeping your current job (10–20h/week over 6 months) - Remote-first culture - Long-term opportunity with profit-sharing potential - Learn faster and deeper than anywhere else — directly from highly experienced quants and developers ⚙️ Process - Short interview (~1.5h) — no LeetCode nonsense, no live coding. Just a real, high-level tech talk between quant/tech nerds. - 6-month paid trial (part-time, ~$15/h) to ensure a strong mutual fit for both sides - Long-term collaboration via Upwork or Upwork buyout, with a competitive package (base + profit-share + VSOPs) Client's questions: Do you have hands-on experience with our tech stack — Rust, Kubernetes, Dagster/Python, Grafana stack, TimescaleDB, and Terraform? Which of these areas would you consider yourself an expert in? Do you have any experience with TB-scale financial data pipelines on top of a Kubernetes cluster? It’s not a must-have, but definitely a nice bonus. Do you have real world experience optimizing intraday trading strategies (in Rust) — from data to optimization to execution? If yes, describe your experience here. We’ll go bit-level deep at our interview, so ChatGPT-style answers won’t help here. Is a paid part-time probation period at $15/h acceptable for you — so we can both evaluate whether this collaboration is a strong long-term fit? Is there anything else you’d like to share about why you think you’d be a great fit for this role? We’d love to hear what excites you about the opportunity!

I run a mixed fleet of Linux and Windows servers and need a seasoned administrator to take full ownership of them. The work starts with a clean, standards-based setup and configuration, then shifts into continuous care: patching, user and permission hygiene, log reviews, capacity planning, and rapid incident response. Security is a priority, so hardening, firewall rules, malware protection, and routine vulnerability checks all sit inside the remit. These machines sit across a combination of on-prem hardware and cloud instances, so comfort jumping between the two is important. I expect proactive monitoring—think Prometheus, Grafana, CloudWatch or similar—so issues surface before they become outages, along with clear, well-commented documentation I can hand to auditors or new team members. Key deliverables • Initial server audit with an actionable report • Hardened builds (both Windows and major Linux distros) ready for production • Automated backup and recovery plans that have been tested end-to-end • A monitoring and alerting stack in place, with agreed-upon thresholds • Monthly maintenance summary detailing updates applied, incidents handled, and any recommendations If you have a track record of keeping mixed-OS environments stable, secure, and performant, I’m ready to get started.

You’ll be the guardian of uptime, reproducibility, and data integrity, setting the baseline for a future SOC 2/HIPAA-ready operation. You’ll Build A containerized CI/CD pipeline to deploy all Zoinova services quickly and consistently Centralized logging and observability stack with metrics, tracing, and alerting Secure cloud infrastructure using least-privilege access and automated secrets management A unified backup and recovery process to protect core data and model assets Key Deliverables (First 90 Days) Deploy fully automated CI/CD pipelines (GitHub Actions or GitLab CI) for all microservices and shared components. Implement centralized monitoring and logging via ELK, Prometheus + Grafana, or equivalent stack. Establish baseline IAM and RBAC policies (OAuth 2.0, least privilege, multi-tenant separation). Harden environments with Linux security baselines, container scanning, and encrypted storage. Automate daily backups and environment recovery scripts (Terraform + S3/GCS snapshot workflows). Success Indicators All core products deploy through a repeatable, containerized CI/CD process. Logs and metrics are unified under a single observability dashboard. Role-based access and key management audited and verified by internal review. Backups complete and restore successfully in test environments. No critical security findings or downtime during the final 14-day test window.

What’s your workflow for tracking progress, sharing updates, and managing deployments when working fully remote? If a system outage or build failure occurred near a milestone deadline, how would you prioritize response and communication? Have you worked in milestone-based or partially equity-compensated projects before? What appeals to you about contributing to a shared AI platform?

I want to set up a logging system that collects logs and sends them to Grafana Loki. Please provide detailed step-by-step instructions and code examples. I need a project similar to this one: https://md-hasanuzzaman.medium.com/comprehensive-guide-to-logging-and-monitoring-with-grafana-loki-and-opentelemetry-in-docker-a7eeeb9efa2c However, I don’t want to use the .NET project part — meaning I don’t want my application to send logs directly to Loki. Instead, I want to collect the logs separately (for example, from files or containers) and then push them to Loki using OpenTelemetry Collector or another suitable client. Please also include ideas for evaluating the setup — for example, how to verify that logs are being collected, transformed, and pushed to Loki correctly.

We are an MSP (Managed Service Provider) seeking a developer to help us build an on-premise solution that can automatically detect correlations across Autotask tickets and provide near real-time insights to our engineering team. The goal is to identify when multiple users are experiencing the same or similar issues within a short period of time, and then trigger notifications and summaries for our team. Scope of Work Autotask Integration - Ingest tickets from Autotask via REST API or webhooks. - Store metadata (ticket ID, category, description, config item, timestamp). Vector Database & Embeddings - Generate embeddings for ticket titles/descriptions (using open-source models such as sentence-transformers). - Store embeddings + metadata in a local vector database (pgvector or Qdrant). - Implement similarity search to detect clusters of “same-ish” issues. Correlation Logic - Define thresholds (e.g., 3+ similar tickets within 24 hours). - Automatically flag clusters as potential “problem tickets.” LLM Integration - Deploy an open-source LLM locally (Mistral 7B, LLaMA 3, or similar) using Ollama or vLLM. - Implement Retrieval-Augmented Generation (RAG) to summarize correlated tickets and generate plain-language updates for engineers. Notifications / Outputs - Send alerts to our team (email or Teams webhook). - Optionally, create new “problem tickets” in Autotask via API. - Build a simple dashboard (Grafana, Flask app, or similar) to visualize active issue clusters. Technical Environment (on-prem only, no SaaS) - Autotask REST API - Python (FastAPI/Flask, sentence-transformers) - PostgreSQL + pgvector (preferred) or Qdrant - Docker / Docker Compose - Local LLM hosting (Ollama or vLLM) - Linux servers (with GPU optional, but preferred) What We’re Looking For: - Proven experience with Python backend development - Prior work with Autotask API (or similar PSA/ticketing APIs like ConnectWise) - Hands-on with vector databases (pgvector, Qdrant, Milvus, or Weaviate) - Familiarity with embeddings & semantic search - Experience deploying open-source LLMs locally (Ollama, Hugging Face, vLLM) - Comfortable working with Docker and on-prem Linux environments - Knowledge of alerting integrations (SMTP, Teams/Slack webhooks, API automation) Deliverables - Working on-prem pipeline (Autotask → Embeddings → Vector DB → Alerts/LLM) - Documentation for setup, operation, and ongoing maintenance - Basic alerting + dashboard showing detected clusters To apply please include: - Examples of similar projects you’ve built (especially integrations with Autotask or other PSA systems). - Your preferred vector DB + LLM stack for this project. - Rough estimate of hours or timeline for an MVP.

1) Objectif du projet Construire un back-office web pour gérer la vente et l’exploitation de produits touristiques : demandes/devis, émission (paiement + billets/vouchers), SAV (modifs, remboursements), CRM clients, reporting et comptabilité basique. Doit s’intégrer à : CRM Kanban (pipeline deals) Fillout (forms) Stripe (paiements multi-devise) API de vols / fournisseur de contenu (voir remarque Google) Base de données clients centralisée 2) Flux métier / cas d’usage (user journeys) Demande client (Fillout) → webhook → back-office crée lead + fiche demande. Création Devis (opérateur) : recherche vols/hôtels/transferts via API(s) / catalogue → calcul coûts (multi-devises) → envoi devis PDF/HTML au client (email + CRM). Validation & Paiement : client accepte → paiement Stripe (préférence : 3D Secure + webhooks) → émission automatique (ou manuelle si fournisseur requiert). Émission : création dossier, envoi voucher / billet, stockage PNR/numéro. SAV : demandes de modification, annulation, remboursement partiel → workflow avec états, logs, notifications. Reporting & Comptabilité : marges par devise, commissions, TVA, état des paiements. Export / API interne : endpoints pour CRM / reporting externes. 3) Fonctionnalités clés détaillées A. Gestion Devis & Vente Création / duplication / édition de devis. Templates automatiques (PDF) avec champs dynamiques (client, panier, TVA, conditions). Historique des versions / log d’actions. Champs custom (p.ex. frais d’agence, commissions). B. Émission & Intégration fournisseurs Connecteurs modulaires vers APIs (flight search & booking, hotels, activities). Mode d’émission automatique ou « semi-automatique » (pour GDS nécessitant PNR manuel). Stockage sécurisé des références (PNR, locator). Gestion des annexes (documents PDF, billets). C. CRM Kanban Pipeline visuel (Kanban) pour leads / devis / ventes. Synchronisation bidirectionnelle (ex : Pipedrive / HubSpot / Trello / Notion) via API ou Zapier/Make. Tags, tâches, assignations, rappels. D. Formulaires / Leads Intégration Fillout : réception via webhook + mapping champs → création lead/dossier. Validation automatique des données (email, téléphone, passeport). E. Paiements (Stripe) Paiement en plusieurs devises (USD, EUR, BRL). Support cartes, receipts, webhooks pour état paiement. Paiement partiel / acomptes / remboursements via dashboard. Reconciliation automatique (matching paiement ↔ dossier). F. Base Clients Base centralisée (profil client, historique voyages, documents). Recherche rapide, merge duplicates, champs KYC basiques. Versioning / GDPR / droit d’effacement. G. Multi-devises & Calculs Montants stockés en devise native + taux FX au moment du calcul. Moteur de calculs “type Excel” (formules, colonnes calculées, réutilisables). Option 1 : intégrer une bibliothèque JS type Hyperformula / HyperFormula (sheet-like formulas). Option 2 : exposer une mini-DSL pour règles tarifaires exécutées côté serveur. Calcul automatique marges, commissions, taxes, conversion. H. SAV & Workflow États workflows : Ouvert → En traitement → En attente fournisseur → En attente client → Clos. Tickets liés aux dossiers, assignés, SLA, messages automatiques. Journal d’événements + upload documents. I. Sécurité & Conformité Authentification SSO / 2FA pour admins. Permissions basées rôles (Admin, Ventes, Emission, SAV, Finance). Chiffrement at-rest (PGP/DB encryption) pour données sensibles (passeports, PII). Logs d’audit, conformité GDPR (export / suppression). 4) Intégrations techniques (suggestions & remarques) Fillout : réception via webhook → endpoint /webhooks/fillout. Map champs. Stripe : API + webhooks (payment_intent.succeeded, charge.refunded) ; sauvegarder payment_intent id sur dossier. CRM Kanban : Pipedrive ou HubSpot (fortes capacités Kanban/deals). Synchronisation via API + webhooks. Google Flights : pas d’API grand public fiable pour booking (QPX express fermé) — prévoir alternatives : Amadeus Self-Service, Skyscanner, Kiwi / Kiwi Tequila API, Sabre/Travelport ou agrégateurs (ou partenariats B2B). (Voir sources). TechCrunch +1 Taux de change : utiliser une source fiable (ex : exchangeratesapi, fixer.io, ou service interne) pour conversions horaires et historique. Middleware d’automatisation : Make / Zapier pour flux rapides si besoin (prototypage). 5) Architecture & stack recommandé Frontend : React (Typescript) + Tailwind — UI responsive, pages backoffice (Kanban, tableaux, formulaires). Backend : Node.js (NestJS / Express) ou Python (Django REST) — API REST/GraphQL. DB : PostgreSQL (ACID, multi-devise), Redis (cache + sessions). Moteur de calcul : HyperFormula (client/server) ou exécution côté serveur avec sandbox. File storage : S3 (AWS) ou compatible. Auth & SSO : Auth0 / Keycloak / custom JWT + 2FA. Hosting : AWS (ECS / Lambda) ou Vercel (frontend) + RDS. CI/CD : GitHub Actions. Monitoring : Sentry / Prometheus + Grafana. 6) Données & modèle simplifié (entités principales) User (id, role, name, email) Client (id, nom, contacts, docs, historique) Lead / Demande (source, fillout_id, status) Devis (id, client_id, items[], total_devise, total_usd, taux_fx, taux_date) Order / Dossier (devis_id, status, paiement_id, pnr, fournisseur) Payment (stripe_id, amount, devise, status) Ticket SAV (order_id, type, status, messages) AuditLog 7) UI / UX — écrans prioritaires Dashboard (chiffres clefs, pipeline) Kanban des leads / devis (glisser-déposer) Fiche Devis (édition, calculs, PDF preview) Paiement / Checkout sécurisé (Stripe) Fiche Dossier (PNR, documents, historique, actions SAV) Base Clients (recherche + fusion) Paramètres (fournisseurs API, taux FX, templates) 8) Tests / QA / Sécurité Tests unitaires & d’intégration (≥70% couverture sur core business). Tests end-to-end (Playwright / Cypress) sur workflows Devis→Paiement→Emission→SAV. Pentest léger avant mise en production (auth & endpoints sensibles). Revue conformité PCI DSS pour traitement cartes (via Stripe, réduire scope). 9) Livrables & jalons proposés (ex : 12 semaines) S1-S2 (2w) : Spécifications détaillées + maquettes principales (Figma) — livraison 1. S3-S6 (4w) : API backend basic (auth, clients, leads, devis), DB schema, intégration Fillout & Stripe sandbox — livraison 2. S7-S9 (3w) : Frontend Kanban, fiches devis, moteur calculs, PDF generator — livraison 3. S10 (1w) : Intégration fournisseur vol/hôtel (1 provider), tests E2E. S11 (1w) : SAV workflow, rôles, sécurité. S12 (1w) : QA final, déploiement prod, documentation & formation (1 session). Livrables finaux : code repo, démo en prod/staging, docs API, runbook ops, guide utilisateur. 10) Critères d’acceptation (exemples) Création d’un devis complet avec calculs et conversion devises validé. Paiement Stripe confirmé et lié au dossier. Emission test via fournisseur intégré (PNR reçu). Création ticket SAV et modification d’un dossier (workflow complet). Synchronisation basique vers CRM Kanban (création d’un deal). Backup DB + logs d’audit activés. 11) Estimation budgétaire indicative MVP (core) : 8k€ – 18k€ selon complexité d’intégrations vols/hôtels et qualité UI. Produit complet + 1 GDS : 18k€ – 45k€. (Estimation indicative — dépend du taux freelance / région et du nombre d’APIs à intégrer.) 12) Documents à demander au freelance dans la candidature Portfolio + références sur projets travel / SaaS. Architecture proposée (1 page) + choix tech. Estimation coût & calendrier (jalons). Politique sécurité / GDPR. Exemple d’intégration Stripe et d’un fournisseur de vols (ou mention de partenaires GDS). 13) Points d’attention / risques Accès API vols : Google Flights n’a pas d’API publique pour booking ; prévoir alternatives et budget pour accès GDS/licences. TechCrunch +1 Conformité paiements (PCI) : externaliser au maximum via Stripe pour réduire la surface d’audit. Devis multi-devises : verrouiller rules FX (qui fixe taux à quelle heure ?) — impact sur facturation. SLA fournisseurs : certaines émissions peuvent requérir intervention manuelle.

Shopify Shipping App Development with Middleware	30 - 50 USD / hr	1 day ago	Client Rank - Excellent Payment method verified $13 259 total spent 48 hires, 7 active 68 jobs posted 71% hire rate, 1 open job 40.81 /hr avg hourly rate paid 179 hours paid 4.99 of 35 reviews Industry: Transportation & Warehousing Company size: 100 Registered: Apr 2, 2019 Venezuela PORT ST LUCIE 13:03 5
We are a logistics company based in Latin America seeking an experienced developer to build a complete shipping integration app for Shopify, with a roadmap to extend it to WooCommerce. The app will handle rate calculation, label generation, and shipment tracking by connecting to our own REST API (which provides endpoints for quotes, shipment creation, and tracking). The solution must be platform-agnostic from day one: a lightweight middleware layer will sit between Shopify (and later WooCommerce) and our logistics API — ensuring that, for our system, it’s transparent whether the request comes from Shopify or WooCommerce. Scope (MVP: Shopify + Middleware) 1. Shopify App Carrier Service: calculate shipping rates in checkout (1–3 service options). Post-payment flow: automatically create the shipment, generate label (PDF/ZPL), and add fulfillment/tracking. Tracking webhooks: receive updates and sync shipment status. Optional tracking page via App Proxy or embedded widget. Basic admin dashboard: list of shipments, reattempts, and label downloads. 2. Middleware (platform-agnostic) Lightweight layer for caching quotes, security/token handling, idempotency, retry logic, and observability (logs/metrics). Designed to serve multiple connectors (Shopify today, WooCommerce next) without duplicating business logic. The backend logistics API should not distinguish whether a request comes from Shopify or WooCommerce — same endpoint semantics. 3. Logistics REST API (ours) Integration with endpoints for: store/origin lookup, shipping quotes, shipment creation/cancellation, and tracking (pull and webhook). Proper validation, error handling, and logging. Second Phase (WooCommerce) Develop a WooCommerce plugin that reuses the same middleware for rates, label generation, and tracking. The same developer can do both projects, or we may hire separately — but the architecture must allow seamless reuse. Technical Requirements (must-have) Proven experience building Shopify apps (CarrierService, Webhooks, Fulfillment APIs). Experience creating WooCommerce plugins (actions/filters, production-ready). Strong understanding of REST APIs, authentication (tokens/OAuth), and webhook verification (HMAC). Skilled in Node.js / TypeScript (or equivalent), Redis/KV for caching and retry queues. Ability to design multi-tenant systems with idempotency, rate limiting, and circuit breakers. Cloud deployment: AWS / GCP / Cloud Run / Lambda. Testing: unit, integration, and end-to-end in sandbox stores. Deliverables & Protection Measures Full source code delivered to our private Git repository from day one. All intellectual property rights transferred to the client. Technical documentation, including: Setup guide (README), environment variables, and secret management. Data models, process flows, and architecture diagram. API integration contract (endpoints, sample requests/responses). Operational manual (debugging, token rotation, cache policies). CI/CD pipelines configured for staging and production, with Infrastructure-as-Code if possible. Automated tests and QA documentation. Design specs / mapping for the upcoming WooCommerce connector. All sensitive credentials handled securely (vault or secret manager, never hard-coded). NDA / confidentiality agreement signed before accessing private materials. Acceptance Criteria (Shopify MVP) Rates displayed in checkout with configurable SLAs/services. Shipment automatically created upon payment, with downloadable label and fulfillment record. Tracking updates synchronized through webhook and visible to customers. Middleware includes caching, retry logic, and basic monitoring (latency/error rates). Architecture ready to add WooCommerce without modifying core logic. Nice-to-Have Experience deploying on Google Cloud Run or similar. Monitoring via OpenTelemetry / Grafana / Cloud Logging. Advanced security practices (HMAC, JWT, WAF, strict CORS). Familiarity with ZPL label generation and secure file handling. How to Apply Please include: 2–3 relevant examples (Shopify shipping/fulfillment apps, WooCommerce plugins, or API integrations). A brief technical proposal outlining your stack choice and how you’d design the platform-agnostic middleware (caching, security, retry logic). Your estimated hours per phase and availability. Your rate (hourly or fixed) and possible start date.

B2B SaaS Startup – Algorithmic Trading & Prop Firm Infrastructure	not specified	2 days ago	Client Rank - Excellent Payment method verified Phone number verified $24 596 total spent 21 hires, 9 active 32 jobs posted 66% hire rate, 2 open job 5.53 /hr avg hourly rate paid 1 593 hours paid 4.97 of 9 reviews Registered: Dec 5, 2024 Spain León 18:03 5
We are a B2B SaaS company in the algorithmic trading and prop firm space. We develop white-label technology infrastructure that allows other businesses in the sector to operate, manage, and scale without having to build their own systems from scratch. We provide our clients with: Admin dashboard (for the CEO or team) → to manage accounts, clients, metrics, payments, and certifications. End-user dashboard → where their customers can view their trading metrics, results, approval or withdrawal certificates, etc. Automations (emails, alerts, notifications for phase completions, withdrawals, referrals). Everything fully white-labeled, connected to MetaTrader 4/5, and hosted on our managed infrastructure. 💼 Who This Platform Is For Algorithmic trading companies / EA or bot vendors They sell trading algorithms that operate on brokers or prop firms. Their current issue: they have paying clients but no professional management system — they rely on spreadsheets and lack centralized dashboards or metrics. With our platform: they get a complete system where they and their clients can see real-time performance, bot statistics, drawdown, PnL, etc., without developing anything in-house. “Pass-Your-Challenge” companies or automated funding services They offer bots that help traders pass funding exams (prop firm challenges). Their current issue: they must manage hundreds of accounts simultaneously and track which clients pass or fail each stage. With our platform: they can automate the entire tracking process, see each client’s stage, generate certificates, and even trigger automatic access to the next phase or withdrawal. In short: the system becomes the back-office and data platform powering any company that manages trading accounts for third parties. ⚙️ What We Are Building To support this, we are building a centralized, scalable infrastructure that can connect hundreds or thousands of MT4/MT5 accounts without relying on costly providers like MetaAPI. The system must read account data (balances, equity, PnL, open/closed orders) in real time using investor-password credentials. Nothing is installed on the client’s VPS — everything runs securely on our managed servers. This will be the core technology powering all dashboards for our clients. 📌 Developer Responsibilities Design and build the first version of this centralized infrastructure (Hosted Connector / Node Pool): Manage MT4/MT5 terminal pools running on Windows headless or Linux + Wine. Automatically connect accounts (investor login) and keep sessions alive. Publish account data in real time (via API / WebSocket). Automatically reallocate accounts if a host fails (auto-heal / failover). Develop the collector API and metrics ingestion database (Postgres + Timescale + Redis). Integrate the system with the existing dashboards. Ensure security, reliability, and cost optimization (target: €2–3 per account/month infrastructure cost). 🧩 Suggested Stack Language: Python (FastAPI) or Node.js (Nest/Express) Infrastructure: AWS (EC2/ECS/EKS) or Hetzner/OVH (Windows/Linux hosts) Databases: Postgres + Timescale (for time-series) and Redis for caching Queue/Streaming: RabbitMQ or Kafka Orchestration: Docker / Kubernetes or ECS with auto-scaling Monitoring: Prometheus + Grafana Security: credential encryption, API keys, mTLS, auditable logs ⚙️ Requirements 3+ years of experience in backend and DevOps. Experience with distributed systems and real-time data. Experience running MetaTrader 4/5 on servers (ideally with Wine). Solid understanding of API design, queues, databases, and security. Interest or background in fintech/trading systems. 🕓 Timeline & Deliverables Initial duration: 6–8 weeks (MVP). Deliverables: Node pool capable of hosting and managing 20–50 concurrent accounts. Collector API + structured storage. Deployment and monitoring documentation. Basic live metrics dashboard (connection status, equity, PnL, etc.).

Because prometheus doesn't consider missing value as zero Here is the query in attached query.txt Need someone to fix the query in query.txt to show accurate count i.e 10 instead of zero for above edge case Fixed budget: 30 USD 2 days ago Client's recent history (11 works) Fix helm error while parsing yaml To freelancer: 5 Great work!

We are looking for an experienced DevOps Engineer to build and manage the infrastructure that powers our clients' data platforms. You will be responsible for designing and implementing robust CI/CD pipelines, automating infrastructure deployment, and ensuring the reliability and scalability of systems like Apache NiFi, Kafka, and various databases. The ideal candidate is passionate about automation, infrastructure as code, and site reliability. Key Responsibilities: Design, implement, and manage CI/CD pipelines for automated builds, testing, and deployments (e.g., using Jenkins, GitHub Actions, GitLab CI). Manage cloud and on-prem infrastructure using Infrastructure as Code (IaC) tools like Terraform or Ansible. Deploy and manage containerized applications using Docker and Kubernetes. Implement and maintain comprehensive monitoring, logging, and alerting solutions (e.g., Prometheus, Grafana, ELK Stack). Ensure the security, performance, and reliability of production data platforms. Required Skills & Experience: Proven experience as a DevOps Engineer or Site Reliability Engineer (SRE). Strong expertise with CI/CD tools (e.g., Jenkins, GitHub Actions). Proficiency with Infrastructure as Code (IaC) tools, particularly Terraform and/or Ansible. Hands-on experience with Docker and container orchestration (Kubernetes is a major plus). Experience with monitoring and observability tools (e.g., Prometheus, Grafana). Experience managing infrastructure for data systems (e.g., NiFi, Kafka, MongoDB) is highly desirable. Client's questions: You are tasked with creating a CI/CD pipeline for a complex data application. What are the key stages you would build into this pipeline, and what is the single most important metric you would track to ensure its health? Your app is slow in production, but the logs are clean. How do you find the infrastructure bottleneck? Detail your diagnostic steps, from network to compute to storage. Describe a project where you used Terraform or Ansible to manage a stateful system (like a database or a NiFi cluster). What are the unique challenges of managing stateful vs. stateless systems with IaC, and how did you overcome them?

We are looking for an elite, hands-on Senior Data Engineer to be the technical cornerstone for our managed enterprise support clients. You will be responsible for the health, performance, and optimization of mission-critical, large-scale Apache NiFi clusters. This is not a development role for new projects; it is a high-stakes operational role for an expert who thrives on troubleshooting, tuning, and ensuring the absolute reliability of complex data systems. Key Responsibilities: Act as the primary technical expert for on-prem Apache NiFi clusters under our management. Proactively monitor cluster health, performance metrics, and dataflow execution. Diagnose and resolve complex operational issues, including performance bottlenecks, back-pressure, and connectivity problems. Optimize existing dataflows for efficiency, scalability, and error handling. Implement configuration changes, security patches, and version upgrades in a controlled manner. Collaborate with client teams to understand their data needs and provide expert guidance. Required Skills & Experience: Deep, demonstrable expertise in Apache NiFi, including NiFi Registry and MiNiFi. Proven experience managing and troubleshooting large-scale, high-volume NiFi clusters in a production environment (on-prem experience is a major plus). Strong understanding of JVM performance tuning as it relates to NiFi. Proficiency in scripting (Python, Bash) for automation and monitoring. Experience with monitoring tools like Prometheus and Grafana. Excellent problem-solving skills and the ability to perform under pressure. Client's questions: A critical, multi-stage NiFi dataflow is experiencing severe back-pressure, causing data delivery delays. Describe your step-by-step diagnostic process. What specific metrics, logs, and tools would you use to pinpoint the root cause? Describe your best practices for designing a resilient and observable NiFi dataflow. How do you handle errors, manage state, and ensure that every piece of data is accounted for without relying solely on NiFi's built-in UI? What are the three most common performance bottlenecks you've encountered in a large NiFi cluster? For each one, explain how you would proactively monitor for it and what architectural or configuration changes you would make to mitigate it.

At first, I was a Partnerships Assistant, but then I got promoted to an Executive Assistant to the CEO. I really enjoyed the flexibility of the job and the different tasks I had to do. Igor, Oksana, and Oskars were friendly and easy to communicate with. However, the best lessons I had were from Oksana, especially those related to marketing. I loved working on Content Matrixes and collecting reports for different brands. I'm grateful for the opportunity to work with Igor, and I feel like I've learned much from this experience!

What is even worse, this person was unable or unwilling to follow our exact instructions, hence was able to produce only mediocre results at best, with way too much energy and time required to supervise her. And finally, when it become obvious that collaboration should be terminated, she was not able even to properly transfer duties to another team member, she abruptly stopped communication after transferring only parts of the duties, ignoring request to transfer remained parts. Unfortunately, we can't recommend this person for collaboration.

Senior Market-Making Engineer (Contract) — Cross-DEX Perp Arbitrage Contract: 2–6 weeks (20–40 hrs/week), extendable Location: Remote (must overlap 4+ hrs with Asia/Tokyo time) Compensation: HKD 120– HKD 220/hr (strong) \| HKD 180–HKD 300/hr (senior with production MM bots) Tech Stack: Rust/C++ (hot path), Go/Python (glue), Linux perf, WebSocket/FIX/HTTP The Mission We’re looking for a highly skilled Rust/Python Developer with experience in low-latency market-making systems to build a cross-DEX perpetual arbitrage bot. Your task: ship a lean, production-ready low-latency cross-venue hedger that captures dislocations across perpetual DEXs (initially Aster Lighter) — with post-only entries, passive hedges under 800 to 900 ms, and a fallback cheapest-exit router. You’ll deliver a robust, measurable system complete with a replay harness and metrics dashboards. What You’ll Build (Deliverables) Venue Gateways (MD + Order) for Aster & Lighter -Sequenced, normalized top-of-book -Flat-array order books -Health checks Hedger State Machine -Entry: post-only maker -Hedge: passive on other venue with ≤800 to900 ms deadline -Fallback: cheapest exit = min(Lighter taker (Premium/Standard w/ slip caps), Aster scratch, passive bleed within bands)  Sizing & Risk Controls -Clip sizing by queue-ahead & trade-through rate (λ) -Inventory bands, daily burn cap  Metrics & Logs -Hedge fill-by-800 ms, decay (bps), taker slip p50/p90, scratch costs, net bps/cycle -CSV export + Prometheus/Grafana ready  Replay Harness -Feed NDJSON order-book deltas -Reproduce decisions and PnL -One-command run Expected Outcomes (2-Week Pilot) Week 1: Gateways + basic hedger CLI sim triggering at ≥ 3.0 bps gap 800 ms timer, micro-size live canary Week 2: Cheapest-exit router, IOC micro-clips, metrics/dashboards, replay Targets: ≥ 70% hedges filled by 800 ms (calm windows) op99 internal decision loop ≤ 1 ms Enforced max_taker_slip_bps (Premium ~1.8, Standard ~3.0) Responsibilities Implement low-allocation, lock-free hot paths (book builder, signal calc, order routing). Manage idempotent order lifecycles (partials, duplicate acks, OOO updates). Add sanity gates: 5 sane ticks post-reconnect, no crossed or zero-size tops. Wire up feature flags, structured logs, and minimal runbooks. (Optional extension): Add pair scheduler (activate workers when live gap frequency ≥ target) and integrate additional venues (e.g., Hyperliquid, Extended, etc.). Must-Have Experience Built exchange gateways or OMS/EMS for trading (crypto or traditional). Proficiency in Rust or C++ in production, with performance tuning (CPU pinning, cache-friendly structures, TCP_NODELAY, socket buffers). Strong experience with WebSocket market data, order lifecycles, sequencing, and recovery (REST reconciliation). Deep understanding of market microstructure — spreads, queue position, microprice/OBI, sweep detection, etc. Nice to Have Familiarity with on-chain DEX architecture and cross-venue hedging. Previous experience deploying market-making bots in production. Comfort working independently in a fast-moving, async environment. Note: Candidates can be based anywhere — as long as they can overlap with Asia/Tokyo timezone for at least 4 hours daily. To apply, please send your GitHub, resume, and examples of previous low-latency or market-making projects.
